Dying 55-Year-Old Cereus: Extreme Weather Damage and Propagation

Mature Cereus peruvianus Turning Gray and Woody

A 55-year-old Cereus peruvianus on a front lawn shows large gray, woody sections and dying newer stalks. The owner asks if it's a natural cycle or something else.

Double Weather Whammy: Record Cold Then Record Heat/Drought

Greg notes that many large cacti succumbed to a brutally cold winter followed by extreme heat and drought. Cacti store water, so cold damage can take months to appear. The main trunk is likely compromised.

Only Option: Take Cuttings

If the main trunk is damaged, the plant cannot be saved in place. Greg offers instructions for taking cuttings from healthy sections to propagate new plants. He invites the owner to request the cutting procedure if the plant isn't too far gone.

Key Points

• Extreme temperature swings kill even established cacti.
• Internal damage shows up slowly due to water storage.
• Propagation from firm, green cuttings is the only way to preserve the genetics.
